I found this quote interesting: https://www.reddit.com/r/retrocomputing/comments/tt41ut/beware_cheap_sata_to_ide_adaptors/ The problem could be that the cheaper adapters just pass the commands through unchanged while the more expensive adapters bother to emulate ATA commands SATA drives are not …

During my observation I managed to get another interesting PCI IDE card, the QD8580 with Vision QD-8580 chip.The chip looks like a clone of a existing one, could be National PC87410 from Tekram DC-290N or another unknown,no luck with the datasheet.Both have the legacy header conenctor for the needed …

I wanted to point out that while the speed boost with UM8673.sys is nice in DOS, I have found this driver unreliable if using XT-IDE on a larger FAT32 partition, which is 60 GB in the case of my system. Users with smaller partitions (8 GB or less) have not run into my same problem. Under DOS it was …

Meanwhile I also got a Tekram DC-290N with the National PC87410 where it seems it's better documented. This IO card also have jumpers for INT# selection, here are not populated, but according to the datasheet has a PCI configuration space.Works also in IDE Legacy mode.

I have several boards with this revision, but I played with a AM5x86-133 @66FSB there and that didn't want to POST, so I sticked with playing with my UM8886/8881 mobos with better success.

Are you looking for pinouts or other hardware stuff, or information for programming those? It's unclear whether the UM8673 ever existed as a discrete chip or only within the UM8886A by the way. Pinout, electrical specs, programming...as usual what is written in regular datasheet. The UM8673F …

Thanks for the picture ! Weird that SOYO had a 029A2 as Intel 430LX, 029B2 as Opti, 029C2 as Intel 430NX. I dug thru all the Soyo wayback archives and found next to nothing on any 029*. Oldest for a Pentium bios's found is for 31a so far https://web.archive.org/web/19970729083844/http://www.soyo. …
